Abstract

An electrical connector includes an insulation body having a base and a tongue located in a front end of the base, terminals arranged in upper and lower rows, and a middle grounding plate disposed in the base and extending to the tongue. Terminals in the upper and lower rows are arranged on upper and lower surfaces of the tongue, respectively. The middle grounding plate is located between the upper and lower rows of terminals, and having at least one first hole. An edge of each of two lateral sides of the middle grounding plate is inwardly depressed to form a first groove. The first hole is located between the two first grooves. The insulation body has a first insulation post and a second insulation post, the first insulation post protrudes into the first hole, and the second insulation post protrudes into the first grooves on the lateral sides.

Claims

a middle grounding plate, disposed in the base and extending to the tongue, located between the upper and lower rows of terminals, and having at least one first hole,

wherein an edge of each of two lateral sides of the middle grounding plate is inwardly depressed to form a first groove, the first hole is located between the two first grooves, the insulation body has a first insulation post and a second insulation post, the first insulation post protrudes into the first hole, and the second insulation post protrudes into the first grooves on the lateral sides.

2. The electrical connector according to claim 1, wherein the edge of each of the two lateral sides of the middle grounding plate is inwardly depressed to form a latch slot, and the latch slots are located closer to a front end of the middle grounding plate than the first grooves are.

3. The electrical connector according to claim 2, wherein each of the first grooves is adjacent to a corresponding latch slot on the same lateral side of the middle grounding plate, and each of the first grooves is connected with the corresponding latch slot on the same lateral side of the middle grounding plate.

4. The electrical connector according to claim 2, wherein the first grooves are closer to a centerline of the middle grounding plate along an axis between front and rear ends of the middle grounding plate than the latch slots are.

5. The electrical connector according to claim 2, wherein each of the first grooves is provided with a first inner edge, a second inner edge and a third inner edge, the first inner edge is closer to a front side of the tongue than the second inner edge is, the third inner edge is connected between the first inner edge and the second inner edge, and each of the first inner edges of the first grooves is connected with a latch slot on the same lateral side of the middle grounding plate.

6. The electrical connector according to claim 5, wherein each of the first inner edge and the second inner edge is connected with the third inner edge through an arc-shaped connection portion.

7. The electrical connector according to claim 5, wherein a length of a projection of the first inner edge along an axis between front and rear ends of the middle grounding plate is less than a length of a projection of the second inner edge along the axis.
